This project aims to assist the shrimp industry by developing quality control materials for microbiological testing laboratories in the country. It is recognized that laboratory testing is an integral part in ensuring food safety through accurate measurement. The DOST-ITDI, through the National Metrology Laboratory, has developed its capability in the field of biological metrology for microbial measurement by developing of a microbiological proficiency test (PT) materials and the provision of PT schemes for local laboratories. This is in response to the need for local PT providers in the country. This project will develop the PT material, Salmonella sp. and APC in frozen, shelled shrimps product. The PT schemes are intended for the Bureau of Fisheries and Aquatic Resources laboratories and other microbiological testing laboratories in the country.
